Ab initio electronic structure calculations for Mn linear chains deposited on CuN / Cu (0 0 1) surfaces
In a recent experiment, scanning tunneling microscopy has been used to obtain a direct probe of the magnetic interaction in linear manganese chains arranged by atomic manipulation on thin insulating copper nitride islands grown on Cu (0 0 1). The local spin excitation spectra of these chains have be...
